Title: Motor driving device
Inventor: FUKUDA DAISUKE
IPC: H02M1/38
Filed: 2003-08-26
Abstract: <P>PROBLEM TO BE SOLVED: To reduce unwanted radiation noise produced when output voltage is switched, and, after output voltage is switched, to cause an output-stage switching element to perform low-on resistance operation in a short time.  <P>SOLUTION: When output voltage is switched from "H" to "L" only a low-output buffer 11, low in driving force, is driven. After output voltage is switched, the gate voltage of the output-stage switching element 9 is steeply increased by an high-output buffer 12. When output voltage is switched from "L" to "H" the gate voltage of the output-stage switching element 9 is steeply lowered by the low-output buffer 11, low in driving force, and the high-output buffer 12 of high driving force. After output voltage VO is switched, the high-output buffer 12 of high driving force is turned off, and the output-stage switching element 9 is driven only by the low-output buffer 11 of low driving force. Thus, unwanted radiation noise is reduced when output voltage is switched, and the output-stage switching element 9 is driven with high efficiency.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-09-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a three dimensionally shaped article, which eliminates the effects of fume and scattered powders, and to provide a manufacturing method.  <P>SOLUTION: This manufacturing apparatus comprises a light beam irradiation means 3 for sintering powders in an irradiated portion by irradiating a predetermined portion of a powder layer 10 formed on a stage with a light beam, and a powder feeding means 2 for forming the powder layer onto the stage and an already sintered layer. The light beam irradiation means 3 is arranged at the position deviated from the position directly above an area to be irradiated with the light beam, so as to diagonally irradiate the powder layer 10 with the light beam. The fume produced by heating due to light beam radiation onto the powder layer ascends toward the just above position, but because the light beam irradiates the portion from the deviated position from the just above position, the cloudiness of the light beam irradiation means (when the means is sectioned by the chamber, an aperture arranged in a chamber so as to transmit the light beam) caused by the fume is reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem wherein a conventional motor terminal box keeps a power cable orthogonal to a terminal block so that the electric wire length is shortened when a terminal to be connected is at the center and made longer when at both ends, and as a result longer working time is required and the electric wire may be damaged by forcible work due to such a structure, and also the terminal box body must be enlarged for a terminal block having many terminals, which causes a difficulty in installing a motor.  <P>SOLUTION: The terminal blocks are structured at both sides to face each other in the parallel direction to the leading-in direction of the power cable, or arranged at three directions of both right and left sides and a front to the leading-in direction of the power cable. Wiring work is performed without changing the electric wire length by making further uniform the distances from the led-in power cable to the terminal fittings to be connected. Furthermore, by arranging the terminal blocks at the three directions to the led-in power cable, the dimensions of the motor terminal box is prevented from being enlarged, even when there are many terminals.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
